Timco Timber Screws Wafer Head Exterior Green 8.0x400 Box of 25

These TIMCO Wafer Head Exterior Green Timber Screws are designed as an alternative to traditional coach screws for timber-to-timber applications. Featuring a wafer head for improved clamping and a low-profile finish, they are suitable for various outdoor projects and external applications. The screws benefit from a patented multi-layer corrosion resistant plating that provides substantial protection in harsh environments, including salt spray. Their design includes a TX40 recess and countersunk head, a helix shank to aid debris removal and maximize clamping, and a 50° deep single thread to deliver secure fixing with high pull-out resistance. A patented lubrication enhances insertion time and further supports corrosion resistance, making these screws a durable choice for exterior timber construction.
